The Firing Line Forums - View Single Post - Good clean burning powder for 9mm that won't bulge cases in S&W Shield.

Apparently folks are reading the thread title and not the OP. The quest isn't simply for a clean 9 mm powder. It's for a clean powder that reaches high velocity without bulging cases when fired in a S&W Shield, specifically. I'll edit the title to reflect this.

With 231/HP-38, again, it's faster than Universal so it won't address the bulge issue. That would take a slower burning powder that somehow burned cleanly despite running at lower peak pressure. I'm unaware of the availability of such a thing.
